CHARLES ALKIN, OF CHICAGO, ILLINOIS.

DRAW-BAR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 271,585, dated February 6, 1883,

' Application filed June 20,1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES ALKIN, of Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Draw-Bars, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is a side view of a draw-bar embodying my invention. Fig. 2 is a top view thereof. Fig. 3 is an end view thereof, and Fig. 4 is a plan view of the wrought-iron strap.

Like letters of reference indicate like parts.

Heretofore draw-bars, so far as I am aware, have been made mostly of cast-iron, and hence were not only brittle and liable to be broken, but they are also very heavy.

My object is to render the draw-gear both stronger and lighter than heretolore. This I accomplish by making a strong wrought-iron strap,which, in its central portion, is slotted to receive the coupling-link. This blank or strap I bend to form the head of the bar. In connection with this strap, which is the principal feature of my invention, I also employ other features of construction which I believe to be novel, and all of which I hereinafter fully describe.

A represents a strap of wrought-iron bent centrally, as shown, to form the sides and head of the draw-bar. The rear ends of the strap A meet, as shown, ate, and may there be welded together.

B B are slots in the central part of thestrap A to receive the coupling-links. These slots may be such in number as to receive one or more links. In the example shown three slots are represented; but the central slot only adapts the bar to a single link,in which case the head of the bar may be much smaller than shown.

C is a head-piece, which may be made either ofwood, paper, or metal, or of any other suitable material. This head-piece is pierced, as

shown at b b, to receive one or more couplingpins.

D is a bar of wood arranged behind the headpiece G. This bar, however, maybe made of metal, if deemed best. This head-piece O is countersunk to receive the strap A, as indicated bythe dotted lines shown at b b in Fig. 2. In other respects the draw-gear may be made in any well-known or suitable way. In the example shown the spring-strap D is inbent at its forward ends to engage shoulders d d on the draw-bar, and it is secured to the draw-bar by means of abolt, E, passing through the spring-strap and through acast-iron block in the rear end of the draw-bar.

F is a nut upon the end of the said bolt.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A'draw-bar in which is thewrought-iron strap A, bent around upon a head-piece, substantially as and for the purposes specified.

2. The head-piece O of a draw-bar, adapted to receive one or more coupling links or pins, in combination with the wrought-iron strap A, bent around and holding the said head-piece and adapted to receive one or more couplinglinks, substantially as and for the purposes specified.

CHARLES ALKIN.
